The Logic Circuit Design of Fire Alarm System Device by DNA Strand Displacement

DNA strand displacement acted as a useful tool is most widely used in the majority computing system. In this paper, a four-input fire alarm system device based on DNA strand displacement is designed. The whole reaction course is programmed and simulated in the software visual DSD, which presenting the superb simulation results with inputs and outputs through compiling the procedure for computation device. According to the results of the Visual DSD software, the method of DNA strand displacement by dual-rail circuits is feasible to achieve more complex logic computation. This investigation on the basis of DNA strand displacement by dual-rail circuits may have a great prospect for the development and application in the biological information processing, molecular computing, and so on.
